Our Janes report is live. In it, Sean O'Connor and I examine developments across China’s early warning network. Among the more notable is a unpublicized system resembling a possible land-based derivative of the Type 346 radar. A series of these have been identified along China's littorals. #geoint

I wrote about JUMPSEAT a few years ago. The NRO has not released much that is new, other than the images. Hopefully they will declassify more in the near future. www.thespacereview.com/article/4096/1

A black and white sketch of Mount Hood, seen from a roughly ground level view. It is in a black frame, and on a blue background. Off to the left are a vertically stacked series of smaller images, too small to read. Each is different-looking, but all are black and white miniature versions of posters. The miniature version of the Mount Hood poster is highlighted in white.

Sample images of three monochrome posters each prepared in a line drawing style. One shows Mount Rainier, another Katahdin, and the last one shows Devil's tower. The posters are stacked on top of each other and the Mount Rainier one is partially rolled up.

A vertical-orientation poster titled "The Seven Summits" — it shows black and white sketches of seven different peaks, the highest on each continent. The peak sketches alternate between being positioned on the left and the right side of the poster. Next to each is a label naming the mountain and giving its location. The poster is framed on a blue background.

There's a free ebook, too! somethingaboutmaps.wordpress.com/2024/10/31/a...

If you could share them around, I would be grateful!

Georeferencing is one of my favorite parts of my job. It's just so satisfying to get an old map lined up in the right place and be able to reproject it.

What can history teach us about what happens when a populist strongman with an idiosyncratic taste for low interest rates undermines central bank independence?

A screenshot of the first page of document by Hans Bethe labeled "The Story of Los Alamos." It is a scan of a weathered document and shows classification review marks and classification markings crossed out. On the right, going horizontally up the page, is a handwritten phrase reading "redacted version." The OCR of the first page is as follows:
"the laboratory was established as the the last
of the tour maJor proJeots in the atomic bomb program. the
purpose ot the three earlier proJects vas to manufacture active
materials which could be used in an atomic bomb. 'I'vo of themthe
project of Dr. Lawrence at the University of California
and of Dr. Urey at Columbia University vere concerned vith the
separation of the active isotopes 235 from ordinary uranium using
~o different methods. The third, the Metallurgical La~ratory
at Chicago, developed methods to produce the entirely new element
plutonium by means of a nuclear reaction. All of these proJecte
vere , in the Spring of 1943, at a stage of transition from re-
"
search to actual production. At this stage it seemed appropriate
to establish a furthsr laboratory to investigate the actual construction
ot an atomic bomb.

to more than ten ti~es its original size"

Hans Bethe, the scientist who worked in both the Manhattan Project & USA H-bomb programs, wrote in 1983 a 40 page history called "The Story of Los Alamos."

It seems not to be publicly available online except where I have made it so, free for all: osf.io/thjpk
